실험 절차

A mixture of 21.2 g. of the product of Example 4, containing 62% of 5-methyl-3-phenyl-6-(p-bromomethylphenyl)-isoxazolo[4,5-c]pyridin-4(5H)-one (0.0332 mole of bromo compound) and 7.2 g. (0.160 mole) dimethylamine in 300 ml. toluene is stirred overnight at room temperature. The mixture is filtered and the solid washed with toluene and the solvent evaporated in vacuo. The resulting solid is dissolved in methylene chloride and treated with 2N hydrochloric acid, the precipitate is then filtered, washed with water and ether. The solid is then dissolved in methylene chloride and 2N sodium dioxide and the organic phases separated and washed with water, dried over anhydrous magnesium sulfate, filtered and evaporated in vacuo to give 5-methyl-3-phenyl-6-(p-[dimethylaminomethyl]phenyl)-isoxazolo[4,5-c]pyridin-4(5H)-one; m.p. 159°-161° C.
